Our old lab has very bad hips, but chooses to lay on our hardwood floors instead of his bed during the summer (I assume because it's cooler). It takes him about a minute to lay down, and the sound of him crashing to the floor is painful (and can't be good for his hips), but that's still his preference. Are there any soft but still cool options for him? All the "cooling" beds I see on Amazon seem very similar to his current bed.
